Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

The ocular manifestations of leukemic retinopathy can be divided into secondary manifestations due to hemorrhage and macular edema, and direct manifestations of leukemic infiltration. Case reports about leukemic infiltration of the optic nerve head are rare. We have experienced a case of leukemic retinopathy in a 16-year-old girl. She visited to our hospital due to sudden decrease of visual acutiy on both eyes and confirmed acute lymphocytic leukemia on bone marrow biopsy. In addition to macular edema and hemorrhage due to secondary manifestations of leukocytosis, there were sheathing noted about retinal arterioles, and disc edema were present on both eyes which seems to be the optic nerve head infiltration of leukemic cells.

BACKGROUND/AIMS: Albuminuria is an early indicator of renal damage in type 2 diabetes mellitus, and has been recognized as a risk factor for peripheral arterial disease (PAD). The aim of this study was to assess the association between albuminuria and PAD in Korean type 2 diabetes patients. METHODS: Our retrospective study included 390 consecutive patients with type 2 diabetes mellitus. The ankle-brachial index (ABI) and toe-brachial index (TBI) were used to assess PAD. The urinary albumin-creatinine excretion ratio (UAE) was evaluated by determining the albumin/creatinine ratio (ACR) in the first voided morning urine sample. RESULTS: Duration of diabetes, serum creatinine levels, and UAE were significantly higher in patients with low ABI scores (< 0.9) than in those with normal ABI scores (> or = 0.9). Age, duration of diabetes, and UAE were significantly higher in patients with low TBI scores (< 0.6) than in those with normal TBI scores (> or = 0.6). Albuminuria was independently associated with low ABI (OR = 1.980, 95% CI = 1.001-3.918). It was also independently associated with low TBI and normal ABI (OR = 3.149, 95% CI = 1.260-7.871). CONCLUSIONS: The results of this study suggest that albuminuria may be associated with PAD, including in arteries distal to the ankle joint.

7.A Fatal Case of Infective Endocarditis Caused by Community-Associated Methicillin-Resistant Staphylococcus aureus ST72 in Korea.
Korean Journal of Clinical Microbiology 2008;11(2):129-131
The advent of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has been a worldwide threat to public health for the past decade. We report a fatal case of infective endocarditis caused by a non-USA300, Panton-Valentine leukocidin toxin-negative CA-MRSA clone. This is a serious case of CA-MRSA infection caused by a sequence type (ST) 72 clone, which is one of the common CA-MRSA clones circulating in Korea where serious CA-MRSA infections have been rare.

SPARC, secreted protein acidic and rich in cysteine, is a extracellular matrix-associated protein implicated in the modulation of cell adhesion, migration, cell cycle regulation, and angiogenesis. SPARC is expressed in fibrocytes and endothelial cells involved in tissue repair and invasive malignant tumors in the gastrointestinal tract, breast, lung, kidney, adrenal cortex, ovary, and brain. This study was aimed to characterize the different expression of SPARC in the thyroid follicular adenomas and follicular carcinomas. Immunohistochemical staining was performed in paraffin-embedded tissues of 25 follicular adenomas and 15 follicular carcinomas of the thyroid gland. Immunohistochemically, SPARC was not expressed in the 19 follicular adenoma and 2 follicular carcinoma but highly expressed in the 6 follicular adenoma and 13 follicular carcinoma. These findings suggest that SPARC is a potential diagnostic marker of follicular carcinoma and is helpful to distinguish follicular carcinoma from follicular adenoma without vascular or capsular invasion.

BACKGROUND: Nitric Oxide (NO) has been discovered to be an important endothelium-derived relaxing factor. The exogenous inhaled NO may diffuse from the alveoli to pulmonary vascular smooth muscle and produce pulmonary vasodilation, but any NO that diffuses into blood will be inactivated before it can produce systemic effects. To examine the effects of NO on pulmonary and systemic hemodynamics, NO was inhaled by experimental dogs in an attempt to reduce the increase in pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) induced by hypoxia in dogs. METHODS: Eight mongrel dogs were studied while inhaling 1)50% O2 (baseline), 2)12% O2 in N2 (hypoxia), 3)followed by the same hypoxic gas mixture of O2 and N2 containing 20, 40 and 80 ppm of NO, respectively. RESULTS: Breathing at FIO2 0.12 nearly doubled the pulmonary vascular resistance from 173 56dyn sec cm-5 to 407 139dyn sec cm-5 and significantly increased the mean pulmonary artery pressure from 16 3mmHg to 22 4mmHg. After adding 20~80 ppm NO to the inspired gas while maintaining the FIO2 at 0.12, the mean pulmonary artery pressure decreased (p<0.05) to the level when breathing oxygen at FIO2 0.5 while the PaO2 and PaCO2 were unchanged. The pulmonary vascular resistance decreased significantly and the right ventricular stroke work index returned to a level similar to breathing at FIO2 0.5 by addition of NO into the breathing circuit. Pulmonary hypertension resumed within 3~5 minutes of ceasing NO inhalation. In none of our studies did inhaling NO produce systemic hypotension and elevate methemoglobin levels. CONCLUSIONS: Inhalation of 20~80 ppm NO selectively induced pulmonary vasodilation and reversed hypoxic pulmonary vasoconstriction without causing systemic vasodilation and bronchodilation. Methemoglobin and NO2 were within normal limit during the study.
